DEVICE FOR REMOVING- THREADED NUTS.

Specification of Letters Patent.

Patented July 21, 1914.

Application filed January 31, 1914. Serial No. 815,597.

To all whom 'it may concern y Be it known that I, I-IoLLIs H. HARRIS, a citizen of the United States, residing at Lorain, in the county of Lorain and State of Ghio, have invented a certain new and useful Improvement in Devices for Removing Threaded Nuts, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

This invention is a device for removing threaded nuts from long threaded members such, for example, as bolts, valve stems of pneumatic tires, etc., and the general object is to provide such a device whereby this may be done quickly and easily. It has heretofore been the common practice to remove nuts from such threaded members by a hand wrench or with the fingers, when loose enough to permit, but this process is slow and laborious at the best, while with my device threaded nuts may be rapidly removed from such threaded members.

@ther objects are to provide a device which may be cheaply manufactured, which may be durable and efficient, and convenientv to operate.

A convenient embodiment of my inven-v `removed therefrom; Fig. 2 is a side elevation looking toward the wrench members of the device; Fig. 3 is a vertical longitudinal section through the wrench members; Fig. 4 is a section taken on the line 4 4 of Fig. 3 Fig. 5 is a section taken on the line 5-5 of Fig. l; Fig. 6 is an end elevation of the wrench members.

Referring to the drawings, 10 indicates a suitable bracket-like frame having a suitable base 11 by which it may be secured to a support. This frame rigidly carries at its upper end a stub shaft 12 extending outwardly at one side of the frame, and as shown, this is secured in place by a set screw 13. Rig` 18. The gear is prevented from outward.

movement on the shaft 12 by any suitable means, such as a pin 19, shown in Fig. 2.

Meshing with the gear 14 is a compara tively small pinion 20 having portions on its hub cut away, forming in effect, clutch teeth 21, adapted to engage similar projections or clutch teeth 22 on the end of a tubular wrench member 24, thereby causing it to rotate with the pinion. This tubular member 24 is carried on a stub shaft 25 having a reduced shank 26 fitted into a socket 27 in the frame and secured there by a suitable set screw 28. The pinion 20 is carried by this member, 25, being rotatable on a suitable bushing 29 which is provided with a fiange 30 forming a shoulder engaging the gear.

A shoulder 31 formed on the member 25 en-y gages the other end of the pinion and acts with the flange 30 to prevent longitudinal movement of the pinion. At the other end this tubular member has a contracted portion 35 in which is formed the angular opening 36, adapted to fit any desirable size or shape of nut. When the crank 15 is rotated, the tubular member 24 will be rotated through the gear and pinion described, and any nut fitted into the angular opening 36 will be rotated with this member 24. Accordingly, it is only necessary to insert the `nut in the opening 36, such as shown at 38,

allowing the threaded member to extend either into the member 34 or outwardly, and hold this threaded member against rotation, then rotate the crank in the proper direction to remove the nut. The difference in the diameter from the gear and pinion may be such as to multiply the movement of the hand crank or any other power which may be used on the gear 14, in the desiredrelation thereby providing for the nut being rotated much faster than would be possible in the ordinary way.

In the particular form shown in the drawings, to the exact construction of which I do not wish to be limited, I have shown a means for holding the threaded member against rotation, which is as follows: The nut 38 is shown on the threaded exterior of a stem 40 such as are commonly used in pneumatic tires, particularly in automobile tires. This stem 40 has the usual enlarged head 41 on the interior of the rubber 42, forming the usual inner tube of such a tire. These stems are usually flattened on twov sides as indicated at 43. These flattened sides engage flattened portions 44 in a contracted opening 45 in the outer end of a tubular member 46, which is rigidly mounted I within the member 24. As shown, this member 46 has a reduced shank 48 fitted into a socket in the end of the member 25. The member 25 is provided with notches 49 adapted to be engaged by lugs rigid with the member 46 thereby holding it against rotation while allowing it to be readily removed from the member 25, when the tubular member 24 is removed. The member 46 has an internal bore 50 for the greater pory tion of its length, adapted to receive the` threaded member or stem. The stem is slidvably engaged in the contracted opening 44,

and as the nut 38 is rotated to remove it; from the stem 40, this stem slides outwardly until it is free from the nut. The member 2 4 may be removably Secured to the member 3 25 by any suitable means. As shown I have provided a thumb screw 52 having its inner end sliding 1n an annular groove 53 as it 1s rotated, thereby preventing the member 24 moving longitudinally on the member 25. This member being removable provides for having any desired number of members-24, each having a differentsize of angular opening 26, adapted to fit different nuts, and the member 46 being removable from the member 25, provides for having a number of these members each adapted to engage various shapes and sizes of threaded members. It will be seen that the device might readily be arranged to rotate the threaded l. In a device of the character described,l

the combination of a member having ja socket engaging a nut, a rigid second memberv in fixed axial alinement with said socket adapted to slidablyengage the member on which said nut is threaded, gearing attached to said members, and means attached to said gearing whereby one of the members is rotated with relation to the other.

2. In a device of the character described, the combination of a tubular member having a socket engaging a nut, a member in fixed axial alinement with the tubular member adapted to slidably 'engage the member on which the nut is threaded, each of said members being adapted to prevent the article engaged thereby from rotating in relation thereto, and means for rotating one of these engaging members with relation to the other whereby the nut is removed from its threaded member.

3. In a device of the character described, the combination of a tubular member having a non-circular socket adapted to engage a nut, a tubular member in fixed axial alinement with said socket having means for slidably engaging the member on which the nut is threaded preventing its rotation withrelation with said last named member, allowing it to slide out yfrom the same, gearing attached to one of said tubular members, and means for rotating said gearing whereby one of the tubular members is rotated with relation tothe other.

4. In a device oi the character described, the combination of a tubular member having a non-circular socket adapted to engage a nut, a tubular member within said tubular member having a flattened portion adapted to engage a fiattened portion on the member on which said nut is threadedand prevent its rotation with relation to such member, but allowing a sliding movement therein, means on which one of said tubular members is rotatably mounted, and means for causing it to rotate with relation to the other.
